# spawn

### like a salmon

spawn the current process

[![Build Status](https://travis-ci.org/aerth/spawn.svg?branch=master)](https://travis-ci.org/aerth/spawn)

as seen in:

  * server daemons

  * http servers

  * chat bots

  * long running processes of all kinds

"use *anywhere*!"

  * go routines

  * main function

  * "click to run the program"

  * hook it up to your `signal.Notify()` ?

### Important notes

  * this library sets the environmental variable SPAWNED=N where N is the number of levels into this we are

  * this means if `$SPAWNED` is empty, we know its safe to spawn another process and exit (not an infinite loop).

  * the arguments, environment are carried over to the new process, so consider setting those before calling spawn.Spawn()

  * if your database (or something) is locked you may want to wait until after spawn check to lock the db

  

### Usage

```

import "github.com/aerth/spawn"

if os.Getenv(spawn.SPAWNED) == "" {

  err := spawn.Spawn()

  if err == nil {

    os.Exit(0)

  }

}

```
